No vape is really meant for a lot of people. The first hit is strongest then tapers off real quick. Unlike smoking a bowl or a joint where the next person just burns new material. I am using an aromazap right now and I suppose that could be used by a group of people-kind of. It comes with these little "stems" that you load up for a couple of hits each. They just pop on and off so you could get a few extra stems and each person have their own.

Supersonic- I'm curious how you like it. I never had much luck with the cheaper, glass bowl type, of conduction vapes.
